NDNSKID CHAIN.

Application filed October 13, 1923. Serial No. 668,434.

To ali whom it may cancer/1.

Be it known that I. Jnrrnnsox liLooM', a citizen of the United States, rt-sidin; at Curwensvillc. in the county of (learficld and State of Pennsylvania, have invented new and useful improvements in Xonskid (hams, of which the following is a specification.

This invention relates to anti-skid chains for motor operate-d vehicles, the invention residing in the construction of the tread rings which allowthe tread chains to be arranged at proper angles with respect to the side chains and thus cooperates with r said rings to otter the greatest amount of resistance to any tendency of the vehicle to skid under all conditions.

The nature and advantages of the invention will be better understood when the fol lowing detailed description is read in connection with the accompanying drawing,

the invention residing in the constmction,'

combination and arrangen'ient of parts as claimed.

In the drawing forming part of this application, like numerals of reference indirate similar parts in the several views, and wherein i Figure l is a fragn'icntary plan view of the anti skid device. forming the subject matter of this invention.

Figure 2 is an enlarged view of one of therings above mentioned.

Figure 3 a detail view of one of the links of each treadtchain which connects the la 01' with one of the rings shown in Figure The anti-skid device embodies the chains 10 which are commonly called side chains inasmuch LS they are adapted to he arranged at opposite sides of the vehicle wheel (not. slit-Wu) and adjacent the telly thereof. 'lhcse side chains 10 are connected together by what term tread chains 11, the latter hcinf! arranged in groups of four chains, having their outer terminals connected with the side chains 10, and their corresponding inner terminals associated with the tread ring 12. The tinal link of each tread chain 11 which is associated with the ring 12, is preferably constructed in the manner shown in Figure 3, that is, it is formed with hook like terminals 13 which can be quickly and conveniently .attached to or removed tron-1 its cooperating ring l2lwhen the occasion may require. It

will he noted upon an inspection of Figure 1 that the various groups of the tread rhains are arranged side by side, so that the ad jaccnt pair of chains of each group have their corresponding outer terminals connected to the side chains 10 at substantially the same point, and in this manner, the entire tread surface of the tire equipped With the device is provided with the tread chains to positively prevent skidding of the vehicle under all circumstances.

In Figure 2, I have illustrated an on larged view of one of the tread rings 12, wherein the ring is formed at diametrically opposite points with spaced pairs of ofiset U-shaped portions 14, there being one of these portions for each tread chain 11, and the hook like terminals 13 of the connecting link of each chain is adapted to receive one of these portions 14. It will be noted that all of the U-shaped portions 14 of, the ring lie in the same plane with the body of the ring to properly contact or engagothe tread of the tire, and thus prevent injury thereto. The offset-portions prevent derangement of the tread chains, by preventing the inner ends of the chains from slipping around the ring, and consequently the said tread chains are arranged at an angle with respect to the ring, their position with relation to tho-side chains providing the anti-skid surface for the tire which minimizcs the possibility of the wheel skidding. Furthermore the hook like terminals 13 of each link shown in Figure 3 are received by oneof the U-shaped portions of the rin and by reason of the fact that these termh nals bear against the parallel sides of the U-shaped portion of the ring, spreading or sliding of the particular chain with rela tion to the ring is obviated. Then again, the offset portions of the ring, which are arranged circumferentially about the center of the tread of the tire also prevent skidding of the wheel to a marked degree, and these offset portions thereby cooperating with the anuularity of the tread chains 11 to offer a maximum resistance to the tendency of the wheel to skid under any and all circumstances. The invention in its entirety i 5 very simple in construction and can be manufactured and sold at a. nominal cost.

\Vhile it is believed that-from the foregoing description, the nature and advantages of the invention will be readily a parcut, I desire to have it understood t at I V rcsortpd'to when desired as fall within the skid do not limit myself to what is herein shown and described and that such changes may be 500 e of what is claimed.

aving thus described the invention, I

claim .-portions of U-shape formation, all of said ortions lying in the same plane with the hody of the ring to properly Contact or engage the tread of the tire and prevent injury thereto, and a substantially U-shaped connecting element connecting each of said cross chains with one of the U-shaped portions of said ring, and terminating to provide hooks to receive said portion, said hooks bearing against the parallel. sides of said U-shaped portion to prevent spreading or sliding of the particular chain with re lation to the ring.

In testimony whereof ture.
